Specification of Letters Patent flatenreil Mar. 17, 1914.

Application filed June 8, 1912.

Serial No. 702,616.

To (ZZZ 2117mm it may concern Be it known that I, F mm; H. Herrera, a.citizen of the. United States, residing at Indianapolis, Marion county,and State of Indiana, have invented and discovered certain new anduseful Improvements in Carbureters, of which the following; is aspecification.

My said invention consists in certain improvements in the details ofconstruction of carburetors, relating especially to carburetors havingglass float chambers, and it consists in means whereby such chambers maybe used and attached to the mixing chamber, intercl'u'm geably withmetal chambers and at, the same time provide for a radially adjustablegasolene teed attachment, all as will. be hereinafter more fullydescribed and claimed.

Referring to the accompanying drawings, which are made a part hcreot andon which similar reference characters indicate similar parts; Figure 1is a side elevation of a carbnreter embodying my said invention, andFig. 2 a. central vertical section through the same.

In said drawings the portions marked A. represent the mixing chamber, Bthe gasolone reservoir or float chamber. C an annular casing member, ortop, interposed between said lloat chamber and said mixing chamber, andD the main air supply inlet.

The general construction of said carbureter is or may be substantiallythat of the welbknown l-lcitger carlmreter, which is illustrated herein,or any other form found. appropriate.

The valve 4.0 for controlling the auxiliary aninlet is mounted on aspring 41 arranged to be regulated and operated as more clearlygizplained in my companion application No. a .lid,l)l2.

'lhe mixing chamber A is formed with a central dependingsuction tube 10having the gasolone and air inlet fitting 1.2 on the lower end thereof,in which is mounted the spray nozzle ill.

The ilont chamber consists of a glass bowl l3 supportml by not i l onthe lower end o'l' a. screw-lbreaded shanl'. l5 depending trom thecasliua 12. The inner end of the hot air surmly tube l) is interposedbetween said nut and the lower end of said bowl, a gasket ill-l forminga tip ht joint between them. giasolene inlet :1: and air inlets 2 areprovided in casting 12, as is usual.

The annular casing member or top (i carrying the gasolene supplyconnection C is formed of metal and interposed between the chamber A andthe upper edge 01 chamber ll, a gasket 17 being interposed in an annularrecess between the adjacent edges of said part. 7

As will be readily seen, the loosening of nut 14 permits ring C to beturned to bring the inlet (7 to any side oi the carliureter or to anyposition most convenient to the gasolene supply.

The float 20 is connector l to one end of a pivoted lever Ell, whichoperates valve 92, which controls the flow oi gasoleucthrough channel 23from the supply tank to the reservoir, or float chamber. Bin the wellknown manner.

\Vhat I claim is---- l. A carburetor comprising a easier, con taining amixing chamber.- and av carbureting, chamber extending from one sidethere of, a metal ring carryingthe gasolcne supply connection mounted tosurround said Clll'lflll'lltlllfj, chamber and seat on one side upon anappropriate scat formed onsaid casing, a glass lluat chamber alsosurrounding said carburetinnchai'nhor and formed to seat at its upperedge against said ring, a metal supply lube nmunled on the lower end ofsaid lloat chamber, said carlnn'etiim chamber being provided with a.part adapted to extend through said tuhe'and foruuad screw threaded, anda nut on said serewthreaded end adapted to secure and clamp said severalparts together. whereby they may be adjusted circum'terentiallyindependently of each other, substantially as set forth.

2. A carlmretercomprising a metal mixinp; chamber, a glass lloat chamberand a metal ring carrying: the gasoleue supply connection and interposedbetween said glass float chamber and metal mixing chamber and supportedto be adjusted circmntercn tially. substantially as set forth.

A carburetor comprising a metal mi ing: chamber. a circui'u'h'renlially:uljuslable metal ring on the under side of said mir-iingr chamber, apan-clone aupplr atlaehmeut connetted with said rinn. u alas; lionl,chamber adjacent to the lower cdo'r oi' said ring: and a clamping: nutconncrlml with :1 central screw-threzuled shank extending through saidparts and adapted to secure them all together. substantially as =et'l'orlh.

L. A. carburetor comprising a cmlmrcting and mixing chamber formed witha main and an auxiliary air inlet, an air supply tube mounted at thebase of said carbureting chamber and adjacent the main air inlet capableof circumferential adjustment, a float chamber surrounding saidcarbur'eting chamber and mounted adjacent said air supv ply tube, and aring carrying the fuel sup- 0 ply to said float chamber mounted between1 said mixing chamber and said float chamber,

and circumferentially adjustable therebetween, substantially as setforth.

In Witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana, this 21st day of May, A. D. nineteen hundred andtwelve.
